.MIXED PH'OLSPHATIC MANURE',

SPECIFICATION forming? part of LettersPatent No. 233,875, dated November 2,1880.

Application filed May 5, 1880. (No specimens.) I

To all whom it mag concern: H

Be it known that I, JOHN G. PERKINS, of Jersey City, in the county of Hudson and State of New Jersey, have invented-certain new and svuseful Improvements in the Manufacture of Artificial Manure or Superphosphate of Lime Compost, of which the following is a full,clear, and exact' description, sufficient to enable oth-. ers skilled inthe art to practicemy invention, said invention being an improvement upon that described and claimed in British Letters Patent No. 1,505, granted. to John William Per- Jkins, A. D. 185?.

The object of my invention is to provide a 1 5 hi ghly-concentrat-ed fertilizery-desi gned tosup- .ply .the stimulation necessary iinorderto promote the rapid growth of Vegetation upon land s which have become impoverished by over-cropping, and where, by-repeated growing of one 2o kind of production, the soil has become deficient in some one or more of the necessary elements torender the same rich and fruitful.

By the application of my improved artificial manure, soil which has become unfit for culti 5 that it may be manufactured at a ery low;

price, and furnished to consumers in large or small quantities. Many productions of this nature are very ofi'cnsive to handle and ship, and greatobjection is made to storing the same;

f 0 but by my improved method of manufacture,

when the manure is completely prepared for use, there is scarcely any odor perceived and the above objections are entirely overcome.

I adopt the well-knowu principle common to 5 I all-inventions of this class of fixing the salts I and odorous gases contained in fish and animal matter and in fecal matter, such as nightsoil, &c.-, by-the use and admixture therewith of sulphuric and hydrochloricacid'.

' it v'. mixing-machine of any approved construction,

I In the process of manut'acturel preferto'nse strong sulphuric acid, not less than 1.66 grav- The sulphuric acid should be placed in a and said machine should be lined with lead, in

'order to prevent the action of the acid upon the material of which itis constructed. At the end of the machine there should be an aperture stopped by a plug, which, when drawn. will cause the machine to discharge itself of its contents.

In my improved method water is added to the sulphuric acid,.and a mixer located. in the machine is set in motion by means of a pulley located thereon and connected with the motive power by-a belt-iirtheusual manner. Raw or 6 5 distilled bones'and animal-charcoal are then put into the mixergand coprolite or mineralapatite in fine powder is added. Having previously prepared and mixed, upon a suitable mixing-fioororin a suitable vessel, sugar-scum, 7o night-soil, raw, fish, or fish-refuse, hard-wood charcoal in fine powder, and castor-pomace or the refuse of the castor-oil bean after the expression of the oil, I add thereto hydrochloric acid. This compost is then placed in the mixer along with its previous contents, as before described, and is fed gradually to the machine.- .The heat resulting from the action of the acid upon the animal and mineral matter will cause the same to dry out completely, still retaining all the valuable elements necessary for stimulating the growth of vegetation.

By my pec'uliarmode of mixing and the use of the mixing floor I am enabled to dispense with the usual complicated and expensive steam-boilers, furnaces, &c., and the serious accidents which frequently occur where heat is eln ployed,from the boilin g ove! of the mixture, are entirely obviated, and the cost of preparing my improved artificial manure greatly reduced. In order to make, say, thirty-five hundred pounds of my improved artificial manure or superphosphate ot' lime-compost, I employ the followingingredients, but any slight variation from the proportions as given will not mate- 5 rially deteriorate the completed product: I take of chloride of sodium, three hundred pounds;

sulphate of lime, four hundred pounds; i'at marl, two hundred pounds; ashes from calcined leather-shavings and t0bacco-ash, each one hundred pounds; nitrate of soda and sulphate of ammonia, each twenty-five pounds; sulphuric acid, six hundred pounds; water, thirty gallons; fish or fish-refuse, six hundred pounds; night-soil, six hundred pounds; castorpomace, one-hundred pounds; mineral apatite or coprolite, in fine powder, eight hundred pounds; raw .or distilled bones, six hundred pounds; animaLcharcoal, two hundred and twenty pounds; sugar-scum, four hundred pounds; and hard-wood charcoal, seventyfive pounds.

When the ingredients are compounded and mixed substantially in accordance with the foregoing description, the resultant product will he 'found to admirably answerthe purposes for which it is intended.

This article may be put up and packed for shipment in bags, barrels, 850., and being in a fine dry powder it may be sown broadcast or applied with a seed-drill, and it will be found equal to Peruvian guano in its fertilizing properties, more lasting in the soil, and can be sold at a much less price per ten.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, isv As a new article of manufacture, an artificial manure or snperphosphate of lime compost, the same being composed of sulphuric acid, water,

animal-charcoal, raw or distilled bones, marl,

mineral apatite or cop'rolite, sugar-scum, nightsoil, raw fish or fish refuse, hard-wood chartwo witnesses.
